Title:
CONTROL APPARATUS FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2013147233
Kind Code:
A
Abstract:

To prevent degradation of an operation feeling during long distance travel while a battery and an electric generator of an electric vehicle of range extender type having the electric generator driven by an engine are reduced in size.

A control apparatus for an electric vehicle predicts whether to or not to perform (to travel on an expressway) long distance travel based on information from a navigation device 19, and the like, and determines whether or not remaining capacity of a battery 16 is less than a predetermined full charge determination value, and drives the electric generator 12 by power of an engine 11 to charge the battery 16 with generated electric power of the electric generator 12 when it is determined to perform long distance travel and the remaining capacity of the battery 16 is determined to be less than the full charge determination value. Thereby, the battery 16 can be brought into a full charge state previously at a time point that the long distance travel is predicted to be performed, so that a situation is avoided where a travel motor 13 is driven only by generated power of the electric generator 12 for traveling when the long distance travel is performed to continue high speed travel for a comparatively long time.
